Abstract

We tested, by means of simulations, the idea of a patterned contact between composite electrode and electrolyte of a SOFC. Simulation results show that the patterned studied geometry can improve the performance of the assembly in “intermediate” conditions, i.e. when there are neither ohmic nor kinetic limitations. The gain reached up to 45 % in terms of current density drawn, with respect to a standard flat contact.
